With Amivox you can communicate at very low rates, especially internationally. Both from your phone and from your computer you can place calls and send sms messages at much lower rates than via traditional means.
they infact give some free credit and you can check it out by calling your dear ones out there and do check the international rates,you have to provide your own number in order to sign up....
hope you will like it :cool:
